Renal disease associated with colic in horses
Modern Veterinary Practice
|May 1, 1984
Summary
Gastrointestinal disorders in horses can cause kidney dysfunction. Early detection of dehydration and azotemia using urine specific gravity and sodium levels is crucial for preventing renal disease.
Area of Science:
- Veterinary Medicine
- Equine Health
- Nephrology
Background:
- Gastrointestinal (GI) disorders are a common cause of renal dysfunction in horses.
- Persistent dehydration (8-10% body weight) can lead to prerenal azotemia, potentially causing renal ischemia and disease if untreated.
- Certain GI conditions like salmonellosis and proximal enteritis frequently result in renal complications.
Purpose of the Study:
- To highlight the link between equine GI disorders and renal dysfunction.
- To outline diagnostic indicators for prerenal azotemia and renal disease in horses.
- To discuss treatment strategies for acute renal failure secondary to GI issues.
Main Methods:
- Analysis of diagnostic indicators including urine specific gravity and urine sodium levels.
- Review of clinical presentations and complications associated with GI disorders.
- Evaluation of treatment protocols for equine renal failure.
Main Results:
- Urine specific gravity <1.018 in azotemic horses suggests potential renal disease.
- Urine Na <20 mEq/L and urine/plasma creatinine ratio ≥20:1 indicate prerenal issues.
- Renal disease associated with disseminated intravascular coagulation (DIC) carries a poor prognosis.
Conclusions:
- Early identification and management of dehydration and azotemia are vital in horses with GI disorders.
- Avoiding nephrotoxic drugs in compromised horses is essential.
- Comprehensive treatment involving fluid therapy, nutritional support, and addressing the underlying cause is key to managing equine renal failure.

01:17Chronic Bowel Disorders: Introduction
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

01:27Inflammatory Bowel Disease I: Ulcerative Colitis
Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...

01:26Inflammatory Bowel Disease I: Introduction
Inflammatory bowel disease is a group of chronic disorders marked by recurrent inflammation of the gastrointestinal tract due to an abnormal immune response against gut microflora. This leads to tissue damage. The two main forms are Crohn’s disease and ulcerative colitis.Crohn’s DiseaseCrohn’s disease is a relapsing inflammatory disorder that can affect any part of the GI tract, from the mouth to the anus. It involves all layers of the bowel wall (transmural) and shows “skip lesions” in which...
01:20Inflammatory Bowel Disease II: Ulcerative Colitis
Ulcerative colitis is a chronic inflammatory disorder of the colon characterized by continuous mucosal inflammation that typically begins in the rectum and extends proximally in a uniform pattern. Its pathogenesis involves a complex interplay of genetic predisposition, immune dysregulation, and environmental influences. These factors converge to impair the colon’s epithelial defenses and promote an exaggerated inflammatory response against luminal contents.Breakdown of the Mucosal BarrierA...
01:20Inflammatory Bowel Disease IV: Clinical Manifestations
Inflammatory bowel disease (IBD) encompasses two major chronic disorders—ulcerative colitis and Crohn’s disease—each characterized by relapsing episodes of gastrointestinal inflammation. Although they share certain clinical features, their patterns of involvement and manifestations differ in ways that aid diagnosis and guide management.Ulcerative ColitisUlcerative colitis is limited to the colon and rectum and involves continuous inflammation of the mucosal layer. The disease course is marked...
